So now to my experiences: Delivery by Amazon: Top!
First impression of the product: The glass bulb is colored slightly bluish, the lamp makes a high quality impression:
First turn on when it is dark: The madness! Pure white light, increased lighting range, excellent illumination of the road in all areas.
Life: There unfortunately there deliver a star. The first lamp was after 3 1/2 months broken at constantly low beam. When removing the lamp is discolored on the inside black. A call to the Bosch Service Center calmed down a bit: The schwarfärbung the piston is normal for this time. These were high-performance lamps that are built to last for ncht but bright and wide to shine. So the Bosch Service Center.
All in all this is so far the best light I had previously installed. That she has persevered only 3 1/2 months is a pity, however, does not stop me from buying this product again.
Last but not least: The illumination on wet roads is fine. One can see everything. and the oncoming traffic is not dazzled, at least I got in this time not because of the flashers
Strong buy recommendation !!!!
